 Electrical Protection

1 Locked-rotor Protection Over-current limiting circuit protects motor from damage at least for 72 hours of locked rotor condition at rated voltage.
2

Maximum Current

under Locked Rotor

A, Typical inrush current when the motor is trying to re-start under locked rotor conditions is 2~4 times the normal running current reoccurring and for 16~20% of restarting cycle period.

B, If he CL function is used this restarting inrush current is about the same as the normal running current.

3 Reverse Polarity Protection No damage if the positive and negative leads are reversed under maximum operation voltage conditions.
4 Over Voltage Protection The circuit will be shut down automatically when input voltage over 284VAC. And re-started when Voltage down to 284VAC below.
5 Soft Start In 5 seconds after power on and speed control voltage gets to 1.5V or PWM duty cycle at 10% above.
